DRZ exhaust swap ?

I have drz 400E model stock... Found full yoshi rs3 for good price. Is the header with yoshi better than stock E? Also will I have to jet and do 3x3 mod immediately?

is the pipe off of an s or sm? the E's have slightly different subframe mounting point.

The full system will be better than a full stock system. If you do put a new exhaust on, it's in your best interest to rejet,

depending on the year of the E it might already have the 3x3 and fcr. what year E?

It's a 2003e do not know ill have to ask if it came off a s or sm?

The stock E exhaust system is fairly free flowing compared to s/sm models...only minor gains will be achieved by changing to an RS3...though you will have an increase in noise , so you mite think it's much better than it actually will be... :confused:

If it's jetted correctly for the E system it should be fine for the RS3...

I believe the E and RS3 headpipe will be the same inside diameter..

I put a FMF Q on my 2004 400E. It is somewhat louder but guaranteed to be 96 or less so it will work in restricted areas. I think the main difference is at the last 1000 - 1500 rpm where the stock exhaust starts to choke up the flow. In the tight Ohio woods I can't really use the difference that much BUT . . . . It weighs 3lbs less (i weighed them both) than stock and lets face it bling is is not just for rappers and girls. It looks a lot better.

So looking like leaving the bike stock is my best bet. Although I can do the 3x3 mod and then jet? What jet works best on stock E

the E's have slightly different subframe mounting point.

Can you expand on this? Can an aftermarket E system fit an SM?

It will ft, but the hole in the subframe is a few mm off (midpipe-ish mount), just have to use a different bolt hole/bracket. not a huge deal.

Have you done this? I have an RS3 slip-on for an E (long story) that I want to mount on my S. Do you happen to have bracket dimensions?

Also, I think I have heard that if you mount an E headpipe on the S it will then allow the E slip on RS3 to fit? Is that true - can someone confirm?

I have not done it personally, but a lot of folks who bought the yosh trc when it was still around had pics of install.

If I remember correctly, it just uses a different hole, instead of the actual pipe mount its like a foot peg hole or something

      I'd like to turn my UK 2004 DRZ400S back to stock airbox (snorkel) and jets, needle shim position etc
      When I bought it the PO had fitted a Sigma6 kit and done the 3x3 mod but is doesn't have a tapered needle like the JD and other kits. Took me ages to get it running right, however it still runs rich and I'm fed up of arsing around with it. 
      So I've bought a standard airbox without 3x3 hole, stock exhaust.
      Q1 The Suzuki manual says this Mukuni BSR36 (29FA) carb should have a 142.5 Main Jet but the Clymer manual say its a 135.  In UK everything's from sea level to 1000m. I'm in Sheffield so nothing gets above 500m even in the Peaks (Hills). Any UK owners or anyone else know what the correct jet should be?
      Q2 Says the original needle is a '5DH36-2nd'. The needle has 5 notches on it. Currently set at 2 clip from bottom. The Suzuki reference says needle is 5DH36-2nd, Does the 2nd bit mean 2nd from top or bottom?
      Q3 - Does anyone have a detailed photo of the shim order just in case it was assembled wrong. (mine is attached)
      I know most people on here are going to be horrified I'm taking back to stock but any help on above would be really appreciated.

      I've read a lot of threads about this but still haven't found exactly what I'm looking for.  I'm pulling my 2004 DRZ400S out of storage sometime this week and getting it ready for the season.  I live at 9,000 ft, but my first ride of the year is probably going to be at around 5,000 ft.  I was going to pull the 145 main jet I'm running and put in the 150 adjusting the needle from the 2 clip to the 3rd, then re-jet once I got home.  I already have the extended fuel mixture screw in place so I started thinking that I should just run the 150 jet set up and adjust the fuel screw to compensate for the higher elevation where I'll be doing most of my riding.  I will be going down in elevation for rides until late May or June depending on snowfall, but riding on the street when I'm able.  Are there any disadvantages with this?
      I'm new to posting on this forum, so please forgive me if I didn't get the right search words in and there is already a post about this.

      Good Morning,
        Last night I measured my valve clearances for the very first time (I know...) on my DRZ400S.  It's a 2002 and I've owned is since 2011.  I bought it with t's got about 15,000 miles on it and most of it's miles these days are on dirt.
      Intake specs are 0.10-0.20 mm.  Exhaust specs are 0.20-0.30
      My intake valve clearances are in spec, forgot to write them down.  My exhaust valve clearances are between 0.1778 and 0.2032 which is slightly out of spec.  They are no more than 25 microns out of spec.  My question is, do I really need to shim these?  Will this kind of out-of-spec cause performance, mechanical, or other losses?  As far as I can tell, I'd have to buy a whole shim kit which is like $80.  Thanks!
